The SOLID principles were introduced by a Software Engineering expert named Robert C. Martin , or “Uncle Bob,” who is well known for writing the books “ Clean Code ”, “ Clean Coder ” and “ Clean Archicteture ” . These principles are closely associated with Object Oriented programming and present a number of techniques and mechanisms for building a more flexible and sustainable class architecture. The term SOLID, although it is an English word with translation of "solid", in this context is an acronym. Each letter corresponds to one of the principles, requiring every term to be capitalized.
